IMPROVEMENT IN HOSE-BANDS.

Specification forming part of Letters Patent No. 210,560, dated December3, 1878; application 'filed August 23, 1878.

To all whom it may concern Be it known that I, FREDERICK W. ROB-ERTSHAW, of Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inHose-Bands; an d I do hereby declare the fol.- lowing to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to/which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification, in which- Figure 1 is a View of the blank; Fig. 2, aView of band ready for use. Fig. 3 shows it in position on the hose.Figs. 4 and 5 are modifications.

This'invention relates to hose-bands, or devices for securing rubber orother hose to the coupling or. ferrule; and consists in the peculiarform and construction as hereinafter 'fully described.

I cast, in brass or other suitable material, a band, A, as in Fig. 1,having the interlocking; catches a at its respective ends, and behindthese the projecting shoulders Z). The ends are correspondingly beveled,as shown. The band A is then bent round into circular form, as seen inFig. 2, in such manner that the shoulders I) are on the outside. In thisform it is slipped over the end of the hose, the ferrule or couplinginserted, and then the band is placed with the shoulders bbetween thejaws of a vise or strong pliers, and compressed till the catches aspring'into engagementwith each other. The hose will now be found to befirmly attached to the eouplin To make the compression more effectualfor griping purposes, I make the band concave longitudinally, orcorrugated, so that the edges or ribs so formed will strike into thehose and compress it into the inequalities of the coupling-ferrule. Forsuch purpose it may have one or more ribs or flanges formed on its innersurface.

Thus constructed, I have a cheap and easilymade hose-band, and one whichcan be attached without the use of special tools, since it can befastened by any vise or strong plierstools which are always at hand.

To detach is just as easy,requirin g simply the insert-ion of a knifeblade or similar tool,

which separates the ends till the catches disengage,when the combinedspring of the metal and hose causes them to fly apart for withdrawal.The same band may be used over and over without impairment of itsusefulness. No riveting, bending, or upsetting be ing required. in itsapplication, itis very convenient, and its construction as simple aspossible.

To prevent liability to being jarred or knocked out of engagement, Iprefer to make the abutting faces of catches a inclined, as shown.

A modification for the same purpose, and also for the purpose of fittingdifferent sizes of hose, is shown by Fig. 4, one end having two or morecatches, a; and the other end bent to give room for adjustment, In this,if the first catch does not sufficiently compress the hose, the band maybe squeezed till the second or third catch engages.

Another modification, which I consider especially fitted for the hose ofrailway-brakes, and such others as are subject to much jarring andjolting, is shown in Fig.- 5, in which all the parts are as before,excep't that one end 's--pe fg a t e gl, and the other,'passing throughits catches, engages with the edge of the slot or hole in' the other. Noamount of rough usage will dislodge it when so constructed.

What I claim as my invention is-- 1. The metallic hose-band A, havingthe bevel-faced interlocking catches a a on either end, substantially asshown and described.

2. The hose-band A, having one end formed with two or more undercutcatches, a, and the other end slotted for its passage, and having theforward edge of the slot acute, substantiall y as described.

3. The hose-band A, having interlocking ends and one or morecompression-ridges formed on its inner face, substantially as shown.

In testimony that I claim the foregoing I have hereunto set my hand this31st day of May, 1878.
